I think you're comparing apples to oranges. I feel your pain but the access to guns is certainly not the issue because it doesn't have to be a fight or flight situation. Did you see the story of Cheran, Mexico? That was a fight or flight and they still won.

It's really not that difficult to exist in Mexico. I've been doing it for 4 years now and I wouldn't go back to that asylum for anything.

When did you start believing in IQ tests? Have you looked into the history of those? I consider them useless at telling us anything other than ability to be conditioned.

As far as the pain of changing vs. not. I think Americans on the whole have lived such easy lives for so long their just like domesticated animals... they can't tell who is friendly and who is a threat. Mexicans on the other hand may look different but are like animals of the wild, they can get along in any circumstance... regardless of what the media tells you about them.

Have you ever seen this episode of the Twilight Zone? I think it explains the problem.
